Isro's Gagan to help planes navigate skyscrapers

Today the prior approval of Air ports Authority of India (AAI) is required for construction of any building more than seven storeys high within 20km of the airport. This restriction will soon be relaxed. Ahmedabad will be one of the first airports in the country to get the Ground-Based Augmentation system (GBAS).

This system helps aircraft take a 'curved approach' before landing and even take-off. The 'curved approach' helps aircraft avoid, with high accuracy, tall buildings in nearby areas. GBAS is currently being tested at Chennai by Honeywell and is likely to get DGCA clearance soon.

Once this system is installed, the Airports Authority of India (AAI) may give speedy clearances for almost 114 tall buildings scheduled to come up in GIFT city, the Central Business District (CBD) on Ashram road and Sabarmati riverfront.
